A raging fire believed to be arson wiped out a 1.2 million-square-foot tissue paper warehouse in California that serves the needs of roughly 50 million people, authorities said April 8. The six-alarm blaze in Ontario, California, happened at a warehouse leased by personal care and hygiene giant Kimberly-Clark early in the morning. There were no injuries to the roughly 20 employees who were in the building at the time of the fire, according to Fox 11 Los Angeles.
